Detailed explanation-1: -Pluto is a dwarf planet in the Kuiper Belt, a donut-shaped region of icy bodies beyond the orbit of Neptune. There may be millions of these icy objects, collectively referred to as Kuiper Belt objects (KBOs) or trans-Neptunian objects (TNOs), in this distant region of our solar system.
Detailed explanation-2: -Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one-it “has not cleared its neighboring region of other objects.”
Detailed explanation-3: -9. The dwarf planet Eris-once thought to be the largest body in the solar system beyond Neptune’s orbit-may actually be smaller than Pluto, new observations suggest.
